Be it known that L Fnennrcn Scironsit... residing at the city of Stqlioi' in the f nite of ll'lissonri. have inve Led re" am new and nsetul lin rovenients in Metalonnlfollowing a full. clear, and exact tlOSCl'll)" tion. reference being had to the accompany-- ing drawings. forming part of this specification. 4 I My invention relates to a metal and wood frame for window screens and has for its objectthe production of a frame of this descriptio'n embodying .1 ni'aximuin degree of strength and rigidity, thus furnishing a "frame which is of marked durability.

Figure I is in part. an elevation and in part a vertical section of my Window screen frame. ,Fig. 11 is a cross section taken throngh the frame. Fig. III is a perspective view of e'fragment ofone of the cross pieces or side pieces of the frame. Fig. IV is a perspective view of one of the corner pieces.

V is across section taken through the bottom cross piece of the frame at the location of oneofthe lifts applied to the frame.

ln the accompanying drawings: A designotes, the side pieces and top and bottom crbss pieces of my metal Window screen frgime. All of these pieces A are constructed ot'sheet netal and each piece comprises a back member 1 extending-the full width of the piece, and a pair of inner and outer box members 2 located upon said back piece and spaced apart from each other to iurnish a groove 3 extending longitudinally between the inner and outer box members and which is adapted to receive strips to be hereinafter more particularly mentioned. The several frame pieces A are initered at their ends so that they may be fitted together to roduce a frame of rectangularshape and in each box hiember 2 of the frame pieces A are per- 't'oraticns 4 that register with perforations in the back member of said frame piece.

5 designates inner and outer metalnngular corner pieces by which the frame p'ieces A are connected to each other. There are two of these corner'hieces located at each corner of the screen inc, one corner piece having its ZU'IHS located in the boxes of the inner coinciding box members that abut against each other, and the other corner piece having its arms located in the boxes of the outer box members of the abutting frame pieces X.

Application file- 3 Llctoncr 5 i. a citiae'ifot the United States oi An ier- We corner p 132 each corner of the by being resumed in the nos nieinhers he fi'rerne pieces A separate from each or end in diner-cot. lines serve to hold the other and to brace the entire frame in an eli'icient manner. The corner pieces are con nected to the frame pieces A; by rivets 7 that are. introduced through the perforations i in the box members 2 of said frame pieces and through perforations 6 in the corner pieces that are adapted to register with the tcrations 4. y

The grooves 3 in the, frame pieces A serve to receive the screen cloth 2 which is stretched across the frame pieces A and this screen cloth is formed with pockets at its edges confined in said grooves by wooden retciner strips 8 of such dimensions as will cause them to fit snu ly in the rooves after the screen cloth has 'een laid t erein. The retainer strips 8 extend the full, lengths of the grooves 3 in the various frame pieces A. and, being of wood, they are naturally yieldin to e. certain de es in order that they grooves to prevent slippage thereof after the retainer strips have been put in place. The retainer strips are held in the grooves in the frame pieces by nails or brads 9 which are driven transversely through holes drilled in the sides of the box members of the frame pieces and which nails or brads, by entering into the retainer strips, serve to hold them rigidly in the grooves in order that they will e ectually retain the portions of the screen cloth in the grooves and cause the sheet of screen cloth to be held tightly stretched upon the frame.

The herein described window screen frame isgadepted to be mounted in metal channel gilxide strips 10, see Figs. 1 and II, that are adapted to be secured to Window frame and in which the screen franie may be raised and lowered; 11, see Fig. is a lift, of which there are preferably two, attached to the screen frame at the bottom thcreoflthis lift being secured to the frame by a strap 12 of pliable material, such as thin sheet metal and which is ironic pieces ii in accurate relations to each.

is provided with grooves extending longituwill tightly hind t e screen cloth in the folded into the groove in the bottom frame dinally of the frame piece, and the outer portions of the box members 2 are so bent that the inner wings of these members extend lrearwardly, (as seen in Figs. II, III, and V,) each Wing bein seated in one of the rooyes 1 properly disposed to receive it. y furnishing the back members of the frame pieces with the longitudinal grooves and extending the inner wings of the box members into said grooves, I provide for said wings being so seated that they will not yield laterally when the retainer strips 8 are.

introduced into the grooves 3;betw.een the box members 2.

I claim:

1. A window screen frame comprising frame pieces each having a back member and an inner box member and an outer box member spaced apart so as to provide a groove between them, inner angular corner pieces connecting the inner box members, outer angular cornerpieces connecting the outer box members, a sheet of screen cloth formed with pockets at its edges occupying the grooves, and retainer strips inserted in the pockets for securing the screen cloth.

2. "A window screen frame comprising frame pieces each having a back member formed with parallel longitudinal grooves,

and an inner box member and an outer box member spaced apart so as to provide a groove between them, and each having the edge of its inner wall inserted into a respective longitudinal groove in the back member, a sheet of screen cloth formed with pockets at its edges occupyin the grooves between the inner and outer ox members, and retainer strips inserted into the pockets for securing the screen cloth.
